Tipping the Scales: Stem Cells May Help Prevent Obesity and More.

Scientists have found that the alteration of stem cell cilia can have a positive effect on weight loss.

 

In a recently published study from the Queen Mary University of London, scientists discovered a connection between the length of cilia [hair-like projections for cell movement] on stem cells and their proclivity towards differentiating into fat cells.  By restricting the elongation of stem cell cilia, the researchers were able to impede on the formation of new fat cells.

Bone Regeneration Made Possible With Stem Cells

Epibone creates precisely measured scaffolding for stem cells to recreate damaged bone.

The New York-based startup Epibone intends to begin human testing on a procedure that will utilize stem cells to regenerate living bone tissue.  The researchers, originally from Columbia University, will apply autologous [the patient’s own] stem cells to nanofiber scaffolding of the desired size and shape and direct the stem cells to differentiate into a physical and genetic replica of the patient’s own bone.

Bone Regeneration Technique Stimulates Stem Cells with Magnetic Nanoparticles.

Remote controlled nanoparticles may allow stem cells to regenerate bone tissue

Medical researchers from Keele University and Nottingham University have integrated remote controlled magnetic nanoparticles to incite the differentiation of stem cells into new bone tissue for the treatment of bone diseases, disorders, and injuries. In pre-clinical trials, the nanoparticles were coated with proteins that stimulate the stem cells, and then delivered directly to the damaged tissue via an external magnetic field. Continue reading

New York Times: The Eruption of Stem Cell Therapies.

Mr. Edgar Irastorza is one of thousands of people already benefiting from the progression of stem cell based therapies.

As reported on the front page of the New York Times Science section, clinical applications of stem cell based therapies are accelerating at a rate that will revolutionize the medical field in a matter of years.  In the United States alone, there are currently over 4000 therapies in clinical trials for the treatment of heart disease, blindness, spinal cord injuries, diabetes, H.I.V., and other diseases, injuries, and traumas.

Stem Cells Immune to Damage from Leukemia Chemotherapy

Certain stem cells have been found to be immune to the bone-degenerative side effects of chemotherapy used against leukemia.

A research team, led by Dr. Eric Darling of Brown University, has found a potential source of stem cells to protect children with acute lymphoblastic leukemia against the adverse effects of the chemotherapy drug methotrexate (MTX).  Adipose-derived stem cells, which appear to be impervious to the bone-degenerative side effects of MTX, may allow children to undergo the chemotherapy treatment and then regain the lost bone tissue afterwards.

Stem Cells Make a ‘Dentin’ Tooth Decay.

Researchers have utilized low-intensity lasers to regenerate lost dentin in damaged teeth.

Researchers at the National Institute for Dental and Craniofacial Research have developed a method of utilizing autologous [the patient’s own] dental stem cells to regenerate damaged or decayed teeth.  In an animal model, as well as human cells in vitro [in a lab], the scientists treated the damaged teeth with low-intensity lasers, which prompted the stem cells located in the dental pulp to differentiate and grow into new, healthy dentin tissue. Continue reading

Hip Replacement Procedure Utilizes Autologous Stem Cells.

Scientists have utilized stem cells to aid in artificial hip replacement.

Doctors and Scientist at the Southampton General Hospital have successfully completed a hip transplant by using a titanium socket and a bone scaffold loaded with skeletal stem cells. The team, led by orthopedic surgeon Douglas Dunlap, 3D printed the titanium implant, and then added the bone graft filled with stem cells to the pelvis to encourage bone regrowth behind and around the metal replacement. Continue reading

Bone Reconstruction Technique Utilizes Autologous Stem Cells

Stem cells are allowing doctors to personalize treatments to repair damaged or diseased bone.

A team of medical researchers at Saint Luc University Clinic have developed a method of repairing bones utilizing autologous [the patient’s own] stem cells.  The process involves harvesting the stem cells from the patient, differentiating the stem cells in-vitro to grow bone, pairing the cells with a scaffolding matrix and then molding the material to repair damaged or diseased bone within the patient. Continue reading

Osteogenesis Imperfecta Treatment with Mesenchymal Stem Cells

Mesenchymal Stem Cell treatment has been shown to improve bone tissue formation in babies with osteogenesis imperfecta.

Researchers from Karolinska Institutet’s Department of Clinical Sciences have developed an application for mesenchymal stem cells [the same type found in Dental Stem Cells] to provide treatment for children born with osteogenesis imperfecta.  The researchers utilized the unique properties of MSCs to facilitate and improve bone tissue formation through in utero transplantations. Continue reading

Athletes Utilizing Their Own Stem Cells to Treat Injuries.

Surgeons utilizing the patient’s own stem cells could significantly reduce rehabilitation times for injured athletes.

Orthopedic Surgeons are utilizing autologous [the patient’s own] stem cells to treat injuries and degenerative diseases in the joints and bones of athletes.  The treatments involve the recovery of the patient’s own mesenchymal stem cells – which are particularly plastic and can differentiate into a variety of tissue types and implanting them back into the damaged bone or joint to reduce inflammation and regenerate damaged tissue without the need for invasive surgery.  Continue reading
